Abstract

An arrangement for charging batteries, the arrangement comprising a battery pack (2) with two or more cell groups (3) connected in series, cell group specific monitoring units (4), and a charger (1) charging the battery pack (2). The cell groups (3) comprise one or more cells. The cell group specific monitoring units (4) are arranged to monitor cell group specifically the voltage of the cell group (3) by leading part of the charging current to flow past the cell group (3) via a by-pass circuit of the monitoring unit (4), if necessary, and comprise means for determining control information (ctrl) to be transmitted to a charger (1). The means for determining control information are arranged to determine the control information (ctrl) in response to by-pass current (Is ) of the by-pass circuit or the temperature of the monitoring unit (4). The charger (1) charging the battery pack (2) comprises means for changing the voltage level of the charging voltage in response to the control information (ctrl) determined by any one of the monitoring units (4).
